Bring back Dim.

X removed the Dim theme. This extension brings it back — with presets and a color picker.

Just shipped Dim for X! Finally got rid of that eye-burning #LightsOut mode. Your eyes will thank you.

I literally live in a cave. I wear all black. My car is black. My soul is black. But even I think Lights Out is too dark. Installed @DimForX — Alfred approves. 🦇

We removed Dim to save mass. Every pixel of gray costs mass. Mass is the enemy of Mars. But I have to admit… this extension is pretty good lmao @DimForX 😂

Settings stored in chrome.storage.sync. Set it once, enjoy everywhere.

Stays in Sync with X

MutationObserver watches DOM changes and inline styles in real-time.

Handles X's atomic classes, inline styles, CSS vars, and modals — all of it.
